/**
* A cross-platform interface that supports platform-specific
* accessibility APIs like MSAA and ATK. Contains the sum of what's needed
* to support IAccessible as well as ATK's generic accessibility objects.
* Can also be used by in-process accessibility clients to get information
* about objects in the accessible tree. The accessible tree is a subset of
* nodes in the DOM tree -- such as documents, focusable elements and text.
* Mozilla creates the implementations of nsIAccessible on demand.
* See http://www.mozilla.org/projects/ui/accessibility for more information.
